(Phys.org) —In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked ...

(Phys.org) —Artificial photosynthesis is a dream technology that mimics a natural leaf, converting water and carbon dioxide into fuels with sunlight. But before this technology can take flight, scientists will have to solve ...

High sugar levels in the body come at a cost to health. New research suggests that more sugar in the body could damage the elastic proteins that help us breathe and pump blood. The findings could have health implications ...

New research shows how the interaction between Atlantic salmon and the ISA virus leads to the development and spreading of the influenza-like disease ISA in fish. The new findings may be of interest to research on influenza ...

(Phys.org) —Researchers at Temple University and the University of Delaware have published a study in the Journal of Biological Chemistry that sheds new light on the clotting effects of a drug that is being tested as a ...

New research from Rice University, Baylor College of Medicine (BCM) and the Puget Sound Blood Center (PSBC) has revealed how stresses of flow in the small blood vessels of the heart and brain could cause a common protein ...

Studied for decades for their essential role in making proteins within cells, several amino acids known as tRNA synthetases were recently found to have an unexpected – and critical – additional role in cancer metastasis ...

Oocytes of lions, tigers and other cat species survive the preservation in liquid nitrogen. Scientists of the Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin succeeded in carrying out cryopreservation of felid ...

(Phys.org)—One of the main reasons that nanoparticles can boost the effectiveness of an anticancer drug while decreasing its toxicity is that they are able to accumulate at cancerous sites in the body through the abnormally ...

Blood vessel

The blood vessels are the part of the circulatory system that transport blood throughout the body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart, the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back towards the heart.
